To all whom 'it may concern:

Be it known that l, RAYMOND C. AGNER,

a citizen ofthe United States, residing at' Burlington, in the county of Racine and State of Wisconsin, have invented a new and useful Lubricator, of which the following is a specification.

This invention relates to that type of lubricators characterized by a hand operated pump, and the object of the present invention is to provide in a lubricator of thiskind an improved forni of plunger, as well as improved and novel means for operating the same.

With the foregoing objects in View the in` vention consists in a novel construction and arrangement of parts'to be hereinafter described and claimedfreference being had to the drawing hereto annexed in which:

Figure l'is an elevation of the pump. Fig. 2 is a central vertical section thereof, partly .broken away. Fig. 3 isa transverse section on the line 3 3 of Fig. 2.

. Referring more particularly to the drawings, 10 denotes the barrel of the pump, the same being in the shape of a cylinder which is closed at'itsends by caps 11 and 12, respectively. 'The cap 11 is screwed o r otherwise removably secured to the dischar'e end of the barrel, and is cup-shaped, and provided with a nipple 13 having interior screwthreads' for the attachment of a nozzle 14 by which the lubricant is directed to the parts to be. lubricated. The nipple is also threaded exteriorly to screw into the lubricant openingof a bearing, and said threaded portion is stepped so that the nipple is given different diameters which enables it to be screwed into different sized openings. By making the cap dished as described, the lubricant will flow more readily, and freely through the nozzle. The cap has a milled edge to facilitate its being turned on croit the pump barrel.

The cap 12 is sWiveled to the opposite end of the pump barrel, by being fastened to a ring 15 encircling the barrel, and loose thereon so that it is free to turn. The cap has a vmarginal flange which extends over the outer periphery of the ring, and screws 16 or other suitable fastening means passing through this flange and into the ring fasten said parts together. rlhe end of the pump barrel has an outwardly directed flange 17 against Aclamped between said disks.

which the ring abuts, and which prevents said ring from slipping od'the barrel.

.The plunger working in the pump barrel comprises the leatherv washer 18 held between' disks 19 and 20, respectively. The disk 19 has a central dished portion 21 whereby a. depression is had in the working face of the plunger. By thus formin a' depression in the working face of the p unger, a better pressure on the lubricant is had, and the same is discharged from the barrel with greater force. The disks 19 and 20 are fastened together by a screw 22 passing centrally therethrough, and the washer 18 is has a central opening to receive the raised portion of the disk 19 on the inner. face thereof formed by the de ression heretofore described. The disk 20 is provided with a stem 23, which is formed integral therewith. The said stem is polygonal in cross section,

and. has ratchet teeth 24 in one of its edges.

rEhe. stem extends through an opening in the cap 12, the shape of said opening correare prevented from catching on-the edges of.

the opening in the cap.

From the ca 12rises a standard 27 to which is pivoted at 28 a lever 29 carryin a pawl 30 which is engageable with the rate et teeth 24 of the lunger stem 23. The pivoted end of the ever is forked as indicated at 31 to receive the standard 27 and also the plunger stem. The pawl is ivotally mounted between the branches o" the forked end of the lever. One end of the pawl is weighted, whereby it is vnormally swung .in a direction to en age the ratchet teeth. A spring may also pose. rihe outer end o the vplunger stem is prvided with a handle 32. mec anism the plunger is advanced in an e em loyed for this pur- The object of this lu and-the the hereindescribed pawl and ratchet l obvious manner to force the lubricant to the parts to .be lubricated. B swiveling the cap 12 on the ump barre, the operatmg mechanism can e` swung around after the pump barrel has been screwed into the bearing opening of the part to be lubricated, and it can therefore be operated Withvgreater ease in close places.

What is claimed is:

1. A lubricator pump comprising a barre having a projecting {iange at one end, a ring.v

loosely encircling the barrel below" the flange, a cap'fitting over the flanged end of the barrel, and having a marginal flange engageable With the rmg, fastening means passing vthrough said marginal flange' and the ring, a plunger Working in the barrel, a

aeoaa a lever pivotally mounted on the cap, and a pawl carried by the lever and engageable with the ratchet teeth of the st em., i

2. A lubrcator pump comprlsing a barrel having a projecting ange at one end, a ring loosely encircling the barrel below the flan e, a cap fitting over the flanged end of the arrel, and having a marginal vflange enthe plu-rigenA and' aforesaid' cap having an openmg through which the plunger stem passes, and means for operating'the plunger stem. v

In testimony that I claim the foregoing as my own, l have hereto axed my signature in the presence of two Witnesses.
